I would think the reasoning behind it would be shut the fuel off just like the electric system shut off. I hope I'm understanding it as NHRA intends..

Adger,

The way I read it was that "mechanical non-OEM fuel pumps" was something like a belt driven or cam driven pump. However it did not say non-OEM style so still not sure.

My dad ran a mechanical fuel pump on his alcohol application for a long time. He used a Morse cable on the inside of the car mounted on the dash that ran to a shut-off valve before the high pressure side of the pulley driven fuel pump. The cable was attached to the lever handle and when pulled, would close the valve from inside the car. It would need to be manually reset.

You should not add a fuel line to the inside of the car. If I can find some pictures I'll post them here.
